The Benevolent Burglary (The Saint TV Series)

Plot
The Saint re-encounters a young friend, Bill Fulton, who loves and is loved by Meryl Vascoe, the sweet daughter of a smug millionaire who forbids her to marry a man with no prospects. Vascoe has an exquisite art collection and a state of the art security system but the Saint bets him that he will be robbed within the week. Assorted opportunists seem likely candidates to deflate Vascoe, including the Saint himself, who has been known to break the law in a good cause, but the ultimate identity of the benevolent burglar is surprising indeed.

Origin
This episode was adapted from the short story of the same name from the 1939 book The Happy Highwayman.
